Specification of Letters Patent.

ties and struts permitting ready changeof' blades.

In the accompanying drawings, Figure 1 is an elevation and Fig. 2 isasectional view of a form of the invention employing a blade with asingle cut-ting edge; Fig. 3 is an elevation and Fig. 4 is a sectionalview showing a modification of the construction of Figs. 1 and 2; Fig. 5is an elevation, Fig. (i is a sectional view, and Fig. 7 is a, furtherelevation of a form employing a blade with two edges; Fig. 8 is anelevation and Fig. 9 is a section of a formof holder having two bladesfolding within a handle; Figs. 10, 11 and 12 are elevations of a furtherform adapted for employing a reversible blade; and Figs. 13, 14 and 15are elevations of a further form adapted for the use of a blade with twoedges.

As shown in Figs. 1 and 2, the invention comprises a handle 1 having ahead 2, the latter having the guards 3 on one side, the recess 4 betweentransversely disposed flanges 5 with projecting lugs 6 on the oppositeside, anda strap or tie-bar 7 .integrally formed with the head andextending be tween fixed end connections. A flexible blade 8, having acutting edge 9 and holes 10' in the opposite edge, is sprung under thestrap 7 so that its cutting edge registers with the guards and its backrests upon the flanges with the holes engaged by the lugs, the straphaving a full bearing on the blade throughout its len h, and, inconnection with the struts provided by the flanges, hold ing its cuttingedge down firmly in its correct position parallel to the guards, withavoidance of all tendency to buckle, or separate from the guards, orslip as in existing. constructions. It will be understood that therecess in the head exposes a portion of the inside of the blade, so thatit can be held more readily for inserting and use either cutting edge.

withdrawing it, and that the blade can be turned if desired.

The modification shown in'Figs. 3 and t employs the handle ll'having ahead 12 with the guards 13 along one edge, the recess 14 in and thegrooves 15 along the parallel ed e, and the strap 16 extendlnglongitudinaIly between fixed end connections. lhe blade 17 is providedwith thelongitudlnal flanges or struts 18 which project from the rearportions ofits faces, parallel to the cutting edge 19, the blade beingsprung under the strap and one of the-ribs seated in a Y groove so thatthe cutting edge is held down firmly alon its length in contact with theguards by t e strap and strut. The flanges in the opposite faces permitthe blade to be turned.

As shown in 'Figs. 5, 6, and 7, the handle 20 has. a head 21 with guards22 along parallel sides, parallel straps 23 extending longitudinally ofthe head between fixed end connections, and screws 24 with reduced ends.25 running in barrels 26 on the head. A

flexible blade with parallel cutting edges 28 is slipped under thestraps so that its edges register with the guards, the blade contamingthe holes 29 which pass the ends while engaging the bodies of the screwsso that the latter act as struts and press the middle portion of theblade away from the head,

against the straps whereby the blade edges are held down against theguards along their length.

In Figs. 8 and 9, I have shown a handle 30 having pivoted thereto aholder 31, the latter being provided with the guards 32 along the fronted e, the arallel grooves 33 1n the opposite aces of t he body along therear edge, the recess 34 formed inthe rear of the body, and the straps35 extending longitudinally of the body on each side between fixed endconnections. Flexible blades 36 with cutting edges 37, and along theparallel edges, extending from the respective faces, struts 38, aresprung under the straps and their struts engaged in the groovesso thatthe cutting edges are held firm along their lengths parallel to theguards. There are thus rovided two cutting edges to a slngle guard: inthe plane of thehandle 30 and the tang 39 by which the razor is handledto In Figs. 10, 11 and 12, I have shown a handle 40 having the head 41,the latter bethe line ing provided along the lower edge with guards 42and flanges 43 at the ends of the line of guards, along the upper edgeparallelto the guards with the strut 44 having the eccentric. pivotalconnections 45 with bearings 46 of the body and a strap 47 extendingparallel to the guards and strut between fixed end connections. Theflexible blade 48, with the strut. depressed, is slipped fixed endconnections, the strut being a cam with guards 60 projecting therefromon one side of its axis of revolution and a tail 61 on the opposite sideof the axis. The strut being thrown down, the blade 62 is slipped underthe strap until its edge 63 rests against the lugs, when the cam strutis revolved to lift the portion of the blade in contact therewith andbring the high cam surface 64 and the blade into engagement, when theblade edge 65 and the guards 60 will register. It will be understoodthat this disposition of the cutting edges rovides not only a veryconvenient and e cient means for holding and changing blades, but alsoprovides facility, in the lower edge, for draw cutting, and, in thehigher edge, for thrust cutting, so that shaving about the chin, throat,and lower lip is facilitated.

It will be observed that a holder. having a tie or strap and strut ofthe character described permits the ready insertion and withdrawal ofblades and subjects themin operative position to a tension whicheffectively the plain strut surface 51 .to.

steadies and maintains the cutting edge in the desired relation to theguards.

Having described my invention, I claim 1. In a safety razor, a blade incombination with a holding device comprising an integrally formed guard;a strap extending parallel with the guard between permanent connectionswith the holding device; means for preventing flexure of the bladebetween the strap and the front support for the blade below a planepassing through these points, and means in the rear of the strap forspringing the blade about the same as a fulcrum for the purpose ofpressing the cutting dedge of the blade down along said 2. In a safetyrazor, a holder having a guard along an edge thereof, a pivoted strutadjacent to an opposite edge and a strap extendin between fixedconnections and disposed between said guard and strut.

3.. In a safety razor, a blade, in combination with a holder having aguard, a strap disposed substantially parallel to said guard and apivoted cam on the opposite side of said strap from said guard, saidstrap and cam engaging said blade to said holder and pressing it downalong said guard.

4. In a safety razor, a holder comprising a head having a revoluble camwith guards thereon. v

5. In a safety razor, a blade, in combination with a holder therefor,said holder comprising a body portion, guards fixed along an edgethereof, a cam' having guards pivoted at a farther edge thereof, andengaging means between said sets of guards.

In testimony whereof I have hereunto set my name this 29th day ofNovember, A. 1907, in the presence of the subscribing witnesses.

WM. DIEBEL.
